Laurent Vivier	2c92be50bc	analyze-migration.py: fix extract contents ('-x') errors When we try to use 'analyze-migration.py -x' with python3, we have the following errors: Traceback (most recent call last): File "scripts/analyze-migration.py", line 593, in <module> f.write(jsonenc.encode(dump.vmsd_desc)) TypeError: a bytes-like object is required, not 'str' Traceback (most recent call last): File "scripts/analyze-migration.py", line 601, in <module> f.write(jsonenc.encode(dict)) TypeError: a bytes-like object is required, not 'str' This happens because the file 'f' is open in binary mode while jsonenc.encode() returns a string. The results are human-readable files, 'desc.json' and 'state.json', so there is no reason to use the binary mode.

Chetan Pant	61f3c91a67	nomaintainer: Fix Lesser GPL version number There is no "version 2" of the "Lesser" General Public License. It is either "GPL version 2.0" or "Lesser GPL version 2.1". This patch replaces all occurrences of "Lesser GPL version 2" with "Lesser GPL version 2.1" in comment section. This patch contains all the files, whose maintainer I could not get from ‘get_maintainer.pl’ script.

Alexey Kirillov	14f9cec713	analyze-migration.py: fix read_migration_debug_json() return type Since we use result of read_migration_debug_json() as JSON formatted string, we must provide proper type.

Laurent Vivier	029ff892e1	migration: fix analyze-migration.py script with radix table Since commit `3a38429748` ("Add a "no HPT" encoding to HTAB migration stream") the HTAB migration stream contains a header set to "-1", meaning there is no HPT. Teach analyze-migration.py to ignore the section in this case. Without this fix, the script fails with a dump from a POWER9 guest: Traceback (most recent call last): File "./qemu/scripts/analyze-migration.py", line 602, in <module> dump.read(dump_memory = args.memory) File "./qemu/scripts/analyze-migration.py", line 539, in read section.read() File "./qemu/scripts/analyze-migration.py", line 250, in read self.file.readvar(n_valid * self.HASH_PTE_SIZE_64) File "./qemu/scripts/analyze-migration.py", line 64, in readvar raise Exception("Unexpected end of %s at 0x%x" % (self.filename, self.file.tell())) Exception: Unexpected end of migrate.dump at 0x1d4763ba Fixes: `3a38429748` ("Add a "no HPT" encoding to HTAB migration stream") Signed-off-by: Laurent Vivier <lvivier@redhat.com> Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: Greg Kurz <groug@kaod.org> Signed-off-by: Juan Quintela <quintela@redhat.com>	9 years ago
